Thanks so much for the reply.
I have tried reinstalling two different ways. The first was to run the installation file that is already part of the windows 10 operating system. The second way was to download the latest version from the Windows website. Both cases, the installation was successful and Onedrive functioned properly and had the OneDrive icon in file explorer. And also placed the onedrive.exe file in the appsdata folder.
A day or two later, however, in both install methods, the OneDrive.exe file disappeared from the apps folder and i was not able to launch onedrive. When i went to the control panel to check to see if OneDrive was installed, the app was listed, but the icon looked messed up.
Please advise.
Thanks!
